by touching unclean objects, and had consequently neglected the purification prescribed for such cases. In this case, if he found it out afterwards, he had contracted guilt which needed expiation.
Verse 4
The third was, if any one should “swear to prate with the lips,” i.e., swear in idle, empty words of the lips, - “to do good or evil,” i.e., that he would do anything whatever (Num 24:13; Isa 41:23), - “with regard to all that he speaks idly with an oath,” i.e., if it related to something which a man had affirmed with an oath in thoughtless conversation, - “and it is hidden from him,” i.e., if he did not reflect that he might commit sin by such thoughtless swearing, and if he perceived it afterwards and discovered his sin, and had incurred guilt with regard to one of the things which he had thoughtlessly sworn.
verses 5-6
If any one therefore (the three cases enumerated are comprehended under the one expression כי והיה, for the purpose of introducing the apodosis) had contracted guilt with reference to one of these (the things named in Lev 5:1-4), and confessed in what he had sinned, he was to offer as his guilt (trespass) to the Lord, for the sin which he had sinned, a female from the flock-for a sin-offering, that the priest might make atonement for him on account of his sin. אשׁם (Lev 5:6) does not mean either guilt-offering or debitum (Knobel), but culpa, delictum, reatus, as in Lev 5:7 : “as his guilt,” i.e., for the expiation of his guilt, which he had brought upon himself.
verses 7-10
“But if his hand does not reach what is sufficient for a sheep,” i.e., if he could not afford enough to sacrifice a sheep (“his hand” is put for what his hand acquires), he was to bring two turtle-doves or two young pigeons, one for the sin-offering, the other for the burnt-offering. The pigeon intended for the sin, i.e., for the sin-offering, he was to bring first of all to the priest, who was to offer it in the following manner. The head was to be pinched off from opposite to its neck, i.e., in the nape just below the head, though without entirely severing it, that is to say, it was to be pinched off sufficiently to kill the bird and allow the blood to flow out. He was then to sprinkle of the blood upon the wall of the altar, which could be effected by swinging the bleeding pigeon, and to squeeze out the rest of the blood against the wall of the altar, because it was a sin-offering; for in the burnt-offering he let all the blood flow out against the wall of the altar (Lev 1:15).
